The purpose of this module is to introduce the concept of variation. It begins by defining quality. If we want to produce quality products and services, we must understand what a process is and why it is important that we focus on the process – not the end product or service. Variation is then defined.
To reduce variation, it must be traced back to its source. In the past, variation has been handled through specifications. While specifications are important, they don’t really help improve a process. To improve a process, one must understand what common and special causes of variation are. Statistical control is introduced. The module includes the following:
